Description W. Michael Petullo 2026-08-08 20:38:54 UTC 
Description of problem:

I installed Xen and some related tools by running:

    dnf install xen grub2-efi-modules net-tools bridge-utils

This left Xen unable to boot because Xen's %post script failed to install multiboot2.mod to /boot/grub2/x86_64-efi/multiboot2.mod. I suspect this happened because grub2-efi-x64-modules is a Recommends dependency. I think this might mean grub2-efi-x64-modules might not get installed before Xen's %post script runs.

Running "dnf reinstall xen-hypervisor" after grub2-efi-x64-modules had been installed fixed the problem.

Version-Release number of selected component (if applicable):

xen-hypervisor-4.21.2-1.fc44.x86_64
grub2-efi-x64-modules-2.12-60.fc44.noarch
